    Key differences between OTA and OTA2 in WICED?

    GrCa_1363456

      What are the key differences between OTA and OTA2 in WICED?

       

      Do either allow partial update - WiFi Stack only / BLE Stack only / User Application only?

       

      Do both provide ability for code verification?

       

      Are all WICED radios supported by one or the other OTA or OTA2?

          Hello GrCa_1363456

          Please refer the table given in Over The Air update in CYW43907 for the key differences in OTA and OTA2.

           

          Do either allow partial update - WiFi Stack only / BLE Stack only / User Application only?

          >> OTA allows only the application to be updated. OTA2 allows the update of the entire application+ firmware + filesystem. OTA2 does not allow partial update.

           

          Do both provide ability for code verification?

          >> I am inferring this as whether the updated image which is OTAed is verfied on the device?

          OTA and OTA2 check for a valid image before loading the new image.  

           

          Are all WICED radios supported by one or the other OTA or OTA2?

          >> Yes. OTA2 is supported only in CYW943907/54907. Rest of the devices support OTA.

           

          The docs directory in WICED(@WICED-Studio-x.x\43xxx_Wi-Fi\doc\) contains documents on WICED-OTA and WICED-OTA2.
